TY? E-WRITING MACHINE.

Farines ann Fireman HAs'rrNGa Ro'rnwnm., both subjects of the King of Great Britain and ireland, residing at Lynwood, Huyton, Liverpool, England, have invented a new ani?. useful mproveinent in Type-friting ls/aehines, et which the gtz'ilowing is a specification.

This invention has reference to typewriting machines, and-whites to the formation or eonstruetion of the type arms o tsueh inaeliines. Y

In the annexed drawings Figure 1 is a front or face view of a type arm formed according to this invention. Fig. 2 is an elevation illustrative of the ordinary hell leverarrangement hy which such type arms :ire aetuated hy the ordinary key levers. Fig. lis a sectional plan of the hearings in which such type arnis are pivoted. Fig. 4 is a plan and Fig. 5 is a side elevation, showing; the general arrangement of a typewriting machine possessing typearins accordingr to this invention.

lt will he noted that the type arm illustratml, carries three types, namely, small letters, capitals, and 'gures, either o which is caused to print by shifting the position or. the platen roller hy i'neans of shift keys.

The type arms l are similar in shape to two sides of a triangle, the type block 2 heing attached thereto near the apex of the angle, while the arms are pivoted :it their iower extren'iities or hase of the triangle. The journals orv pins 3 which forni these pivots are ceneri at each end and lie in simiiarly eonerl soelo-,ts in the type arm frame 4. A single sere-veci stud 5, bearing upon the middle or cylindrical. portion of the pin 3,

between its eoned ends, serves to centralize such pin 3 in its eoned socket and thus maintain a true bearing. The axis of the pivot pins 3 forms in conjunction with the two limbs of the type arm a perfect triangle. onsequently an extremel rigid eonstruction of type arm is aiorde and any afijustment thereof must be effected at their pivot hearings. A bank of such pyramidal arms is arranged on each side of the machine, their apexes resting upon a suitable saddle piece 6. Each type arm 1 possesses a cranked extension 7, which maT7 be coupled in any suitable manner, as or example, by means of the rod 8, hell lever 9 and pull 10, with the levers ll of the type keys l2. v

1l aving now described our invention, what we caim as new and desire to secure by Letters Patent is#M 1. In combination a V-shaped type arm, :ilined journals on the extremities of said arm, the axis of which journals forms, withl the sides of the Vtype arm, a substantially triangular figure, a type-block on the arm near the apex oppoite the ot' the journals, and a lateral extension on one of said journals for actuating said arm; substantially as described.

2. ln combination, a. V-shaped type arm, double eonerl journals on each extremity of said arm, a supporting frame having correspondingly eoned recesses therein to receive said journals, and a stud for eenterin said journals in 'their sockets; substantie ly as described.
